Tire Pressure Monitor System
If your vehicle has the tire inflation monitor system, it
can alert you to a large change in the pressure of
one tire. The system“learns”the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire inflation monitor system
won’t alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle is
moving faster than 70 mph (110 km/h).
The tire inflation monitor system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a low
tire—but it doesn’t replace normal tire maintenance.
SeeTires on page 5-56.When the LOW TIRE light comes on, you should stop
as soon as you can and check all your tires for damage.
(If a tire isflat, seeIf a Tire Goes Flat on page 5-66.)
Also check the tire pressure in all four tires as soon as
you can. SeeInflation—Tire Pressure on page 5-57.
The LOW TIRE light will also be displayed (while
the ignition is on) until you reset (calibrate) the system.
Don’t reset the tire inflation monitor system without
first correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you
reset the system when the tire pressures are incorrect,
the system will not work properly and may not alert
you when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire inflation monitor system.
You’ll also need to reset the system whenever you
buy new tires and whenever the vehicle’s battery has
been disconnected.
To reset (calibrate) the system:
1. Turn the ignition to RUN.
2. Locate the red RESET button inside of your
instrument panel fuse block.
The fuse block is located under the cover labeled
FUSES, which is at the end of the instrument panel
on the passenger’s side of the vehicle. The
RESET button is thefirst button in the top row of
the fuse block.

3. Press and hold the RESET button for aboutfive
seconds.
The LOW TIRE light will come on andflash three
times. Then it will go off. If the light doesn’tgo
off, see your dealer for service.
The system completes the calibration process during
driving.
The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to“learn”tire pressures.
The speed ranges are 15 to 40 mph (25 to 65 km/h),
40 to 65 mph (65 to 105 km/h) and above 65 mph
(105 km/h). When learning is complete, the system will
alert you after two to eight minutes if a tire is 12 psi
(83 kPa) different from the other three tires. Detection
thresholds may be higher and detection times may
be longer on rough roads, curves and at high speeds.
The system is not capable of detection at speeds greater
than 70 mph (110 km/h).Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-60andWheel Replacement
on page 5-63for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. Thefirst rotation
is the most important. See“Part A: Scheduled
Maintenance Services,”in Section 6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire rotation.
5-59

After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label.
Reset the Tire Inflation Monitor System. SeeTire
Pressure Monitor System on page 5-58.
Make certain that all wheel nuts are properly tightened.
See“Wheel Nut Torque”underCapacities and
Specifications on page 5-92.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. See“Changing a Flat
Tire”in the Index.
When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following statements
are true:
•You can see the indicators at three or more places
around the tire.
•You can see cord or fabric showing through the
tire’s rubber.
•The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
•The tire has a bump, bulge or split.
•The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.

Storing the Spare Tire and Tools
When storing a compact spare tire in the trunk, put the
protector/guide back in the foam holder.
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon
as you can. SeeCompact Spare Tire on page 5-77. See
the storage instructions label to return your compact
spare to your trunk properly.
Be sure to calibrate your low tire pressure system after
you replace your compact spare tire with a full-sized
one. SeeTire Pressure Monitor System on page 5-58.A. Retainer

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you canfinish your trip and have your full-size
tire repaired or replaced where you want. You must
calibrate the tire inflation monitor system after installing
or removing the compact spare. SeeTire Pressure
Monitor System on page 5-58. The system may not work
correctly when the compact spare is installed on the
vehicle. Of course, it’s best to replace your spare with a
full-size tire as soon as you can. Your spare will last
longer and be in good shape in case you need it again.
Notice:When the compact spare is installed,
don’t take your vehicle through an automatic car
wash with guide rails. The compact spare can
get caught on the rails. That can damage the tire
and wheel, and maybe other parts of your vehicle.Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’tfit. Keep your spare tire
and its wheel together.
Notice:Tire chains won’tt your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst intoflames if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed
space. When you use anything from a container to clean
your vehicle, be sure to follow the manufacturer’s
warnings and instructions. And always open your doors
or windows when you’re cleaning the inside.
